I haven't kept track for a while, but whoever I knew that used arc, they found it hard to go back to standard browsers after getting used to its various UI affordances. Even when they pulled the "you need an account" thing most people I knew just sucked it up and created an account. I am assuming a good portion of them will submit to whatever atlassian demands.

why not Zen https://zen-browser.app/ ?

I've found it just as good AND it's open source https://github.com/zen-browser/desktop

Because for better and for worse - it is Firefox.
